Semi-automatic weighing and packing line type WB/S
Market demand has led us to design a semi-automatic weighing and packaging line, type WB/S, which combines dosing precision, relatively low cost, and ease of operation. The WB/S line is a semi-automatic weighing and packaging device for bulk/powdery products using open-type bags. The presented line has a weighing system mounted on the spout, called a groove system, which means that the product is dosed directly into the packaging via screw conveyors of various diameters.
Basic subassemblies of the appliance:
- Line supporting structure with a service platform
- Electronic batching scales of the gross type – 2 pieces
- Screw feeder
- Open mouthpiece
- Belt conveyor for transporting bags
- Belt conveyor height adjustment system
- Bag top guiding system
- Single-thread stitcher
- Side belt conveyor collecting bags with a system for overturning bags
- Clear control system based on Siemens PLC controller with a touch panel
- Applied SEW or LENZE drives / servodrives
Optional equipment:
- System for folding bag top
- System for applying crepe tape
- System for sucking out product in a bag
- Filled bag vibration system
- Feeder cleaning system
- Impulse or continuously heated sealing unit
- Double-thread stitcher
- Balancing container located above the scales
Basic technical parameters:
- Maximum batch weight: 50kg,
- Minimum batch weight: 10kg,
- Line capacity: up to 280 batches/hour (depending on the product characteristics and batch size),
- Bag type: open bags, multilayer paper bags (up to 4 layers), envelope-shaped bottom bags without side folds are recommended, PE foil bags, PP polypropylene coated bags,
- Bag width: 450 – 650mm,
- Bag length: 600 – 1100mm
- Power supply: 3 x 400V 50Hz,
- Power requirement: max. 4.5kW,
- Compressed air supply: 5 – 10bar,
- Compressed air consumption 200-400Nl/min,
